I’m glad to hear you’re less upset now. I find the past interpretation of “on call” interesting, because I’ve worked in many places and Ive NEVER seen it work that way.
How does that work, exactly? If there is a sick call and they know they will need you for the entire shift, and you don’t have to actually answer your phone until 0700, what does that off-going nurse do? Does she have to stay late while she’s waiting for you to come in, which may not happen until 0730 or 0800?
